These .pulleys are pivotally mounted on pins allfwhich Vare mounted in "the side members cgfofthe frame. VThe panel b is counterbalanced bymeans of a pair of weights h6 which are disposed in the Compartments as.V VFlexible cables 57 which pass over .sheaves bsY connect these weights with the upper ends of the sidebars b4. A molding c? is secured tothe inner face of the wind'ov'vrfranie c for ornamental purposes; Beneath lthe bottom vvmember c is a ledge es ywhich ro'ects out-wardl and forms a sill as Well understood inthe art. As described m so far, the windowr isfof standard or conventional construction and exemplifies the type Vat of constructionV now *usedl for buildings and Alike structures.

The inventionA contemplatestheprovision Vof'a device14 which-.is adapted to prevent the entry of dust through the bottom part ofgthe window opening when the panel a isin any of its open'positions and afdevice 15 v'which is adapted to arrest-dust from entering the upper part of said opening. The device 14 comprises a rollerll and a exiblefscreen '17( which is wound around the roller and is attached to the crossbar ai of the Ysashav so that it will be unwoun'd` and bridge or close .the window opening when the panel a is lifted into any of its raised vpositions. The .screen 17VK is; preferably formed of loosely wevenfabric and serves to 'arrest dust particlesy and Vpermit air to pass through the openingv for.v Ventilating purposes.KV VThe screen is ofsuch width vthat the side` margins thereof extend substanf.

' tially to the side members c2 ofthe Windowframe c.V lThe roller 16 is mounted in close proximity to thelbottom member c and is rotated by a helical spring (not shown) so that it automatically winds the screen there# onV when the panel a is lowered into its closedV position.k [The spring is mounted in an elongated chamber which extends ,lon-y gitudinally through the'central portion of the roller. The ends of the roller are sup- The latter are formed by HIVAthe 'portedc rotatably by a pair of Vsheet metal brackets 19 and 20. These brackets fit against the lower ends of the 'side `members 02 of the window-frame and are arranged so that the lower edges thereof abut against the bottom member c. When the panel a is raised, the flexible `screen 17 will be unwound from fthe .roller 4aud-will cause thelatter to rotate in a direction which results in winding of the spring. vThen the panel .is lowered,"the spring causes rotationof the vroller in the opposite direction and automatically-winds the screen back inplace. The inner end of the screen 17 is secured or anchoredto theroller by any suitable means.l The outerend ofthe roller extends outwardly towards theV ledge 08 and thenl upwardly around a guide roll 67. This roll is connected pivotally Vtoand supported by the lbracketsl'and20. l VThe extreme outer end ofthe screen 17 i is doubled back upon -itself-andis'sewed as at 45 to form a hem 45.*. Astay 47v extendsthrough this hem and `is coterminous'therewith. It is removably heldin place against the crossbar as of the panel a byfa pair of retaining devices 48 so that the outer or distal end of the screen is connected V.removably toA the sash a" ofA thepanel. AThe retainingrdevices 48 are connected to the crossbar a3 by screws 49 land embody upwardly V.extending fingers 423 for securingr releasably the stay 47 to the sash a', Duster dirt is prevented from passing lbetween the .side margins ofthe screenjlT Aand the ksides ofthe window- Aframe byfmeans of Vapair of guide elements 52. vThe'latter comprise fixed members V58 and hinged members 54. The xed members are secured to ther side member c2 of the window-frame directly above the brackets 19 andwQO and embody inwardly extending right anglevfianges 53a which are adapted to lap the ,outer faces of the side margins of the screen. The hinge members 54 embody right angle flanges 54a which are adapted to lap the inner faces'of the side margins of the screen`17; Latches 55 serve to secure the hinged members in their, operative position. When these Alatches'are released,l the hinged members zmay be swung inwardlyso as to swing the flanges 54a out of engagement with the contiguous faces of the side margins ofthe screen.V n y VThe screen device 15 which is associated withA thepanel Z; and the'upper cross member 03' 'ofthe-windowframe is similar in lconstruction/to the device`14. It comprises a spring actuated roller 56`and a loosely wovenfk fabric Vscreen 57. The latter is wound around the .roller 56 and hasy the outer end thereof connectedV by retaining devices 58 to a channel member 60 which is secured to the innerface' of the crossbar b5 by screws 61. Whenthe' panel b is lowered, the screen 57 is unwound from the v'rollerf and i'sedrawn downwardly by theA member 60 so that-ity extends alongside of the strip and closes the gap forfopening at the `top of the frame. When the panel b is'raisedvinto its closedy position,;the screenV is' rewound by the action of the lroller spring. The channel 4members 60 projects inwardlyfrom the cro-ssbar b5' across the path of travel of the panel av and'is in the ing around ythe side margins of the screennature of a lstop which limits ythe lupward vmovement of said panel a. lA characteristic and an advantagelofmounting the screen device l5 for the outer panelon `the inside." Vpart ofthe Window-frame and utilizing the panel lmember 60 is that the ldevice 15 'is protected when the ypanel Ibis in its closedposition and provision is made-for preventing the inner panel from being shifted up-1 ,wardly past the outer panel. VThe spring actuatedroller 56 `of the device 15 is sup' ported rotatablyby brackets 62. f The latter Vare connectedto the upper ends of theside'` members c2. Dust is precluded frompass- 57 by vmeans of guidelelements 63. Thelatter are similar in construction to thegele` ments 52 andare mounted on` the strips c5 in alignment with said elements V52.

To prevent dustand open position, a strip 64 is provided. This i Y stripis secured, to the bottom face Vof the lower. crossbar 't3 ofthe sash b2 and is provided with a strip 66 of felt or similar material which'is `adapted to itagainst jthe panea. f'

The window construction disclosed andillustrated herein is exceedingly eiicient in operation and serves eifectively to preventy n the entry of dust through `the window open- Ving. By virtue offthe fact that both screen. devices arev mounted on the inside Voli-the window, 'the' iiexible screens 17 and'r 57 are! not subjected to snow *andV 'rain when the panels a, and b are in their' closed position.l
